TRH concentration in rat olfactory bulb is undiminished by deafferentation.
The effect of deafferentation of the rat olfactory bulb on bulbar TRH concentration was studied. TRH concentrations in the lesioned bulbs did not decline when compared to concentrations in sham-lesioned bulbs for the post-lesion intervals of 1 h through 14 days. Since TRH concentrations did not decline following deafferentation, TRH in the olfactory bulb does not derive from centrifugal neurons.
